Momentum = 0.5 * 4 = 2
to conclude the man’s velocity after he throws the piece of equipment, divide
this number by the man’s mass.
v = 2/90
This is about 0.0222 m/s. To know if he can move 6 meters at velocity in
4minutes, use the following equation.
d = v * t, t = 4 * 60 = 240 s
d = 2/90 * 240 = 5⅓ meters.
This is ⅔ of a meter from the spaceship. To know the velocity that he must have
to move 6 meter, use the same equation.
6 = v * 240
v = 6/240
This is about 0.00416 m/s.
His final momentum = 90 * 6/240 = 2.25
To know the velocity of the package, divide this number by the mass of the
package.
v = 2.25/0.5 = 4.5 m/s

Answer:Energy is absorbed in exact amounts that correspond to differences in energy levels.
Explanation:
According to Bohr's theory, an electron moves from a lower to a higher energy level when it absorbed photon of a given energy. The energy of the photon absorbed must be equal to the energy difference between the higher and lower energy level. Thus energy is absorbed only in discreet amounts that correspond to differences in energy levels. Absorption of energy in discreet amounts is what is meant by the term 'quantization'.
In order to find the speed per minute you will have to divide the two numbers together. You need to do 36/5.4 so the answer will be around 6.7 feet per minute.
Answer:
712.5 kg m/s
Explanation:
Work out the total momentum before the event (before the collision):
p = m × v
Massof Deon = 95kg
Velocity =7.5m/s
Mass of Chuck = 120kg
Velocity = 0m/s
Momentum of Deon before = 95 × 7.5 = 712.5 kg m/s
Momentum of Chuck before = 120 × 0 = 0 kg m/s
Total momentum before = 712.5+ 0 = 712.5 kg m/s
Working out the total momentum after the event (after the collision):
Because momentum is conserved, total momentum afterwards = 712.5 kg m/s
